Thrads get 'derailed' often.... but in this case it's not quite 'black and white'. This weapon concept naturally raises such issues of 'overkill' [yep, great pun] and war, foreign policy, et al, so it's not necessarily 'off-topic'.

Comments 'shouldn't' be deleted ad hoc just for that, otherwise responses must be as well....and all that is draconian censorship that people justly despise.

Back on topic....a home-grown inventor in Oz with no weapon/balistic background came up with an electric fired tube gun....all the bullets in the one barrel .... that had the capacity to fire at a silly rate of knots .... was so 'good' the US Military got all 'moist' and he probably got rich.

This thingie uses centrifuge....it's the equivalent of the big brat in the schoolyard throwing stones harder and faster than you can.

Morbidly curiously interesting technology....all we need is new and better ways to kill people...

Dunno about that zero inertia B.S. in space....last I heard...every action has an equal and opposite one...so if that's the scope of their physics prowess the whole thing's a dud...
